Hello,
I just build a site using acf with the google map field and it works fine in the test site, but when I moved it to the production server it brokes and does not show the map in the frontend and also in the backend, showing this message instead: This page didn’t load Google Maps correctly. See the JavaScript console for technical details. It seems to be related to the API key, but I donĀ“t understand why works in the test server (http://www.netspace.cl/grana/tienda/puntos-de-venta/region-metropolitana/) and doesn’t in the production server (http://www.grana.cl/undostres/?page_id=497).
Any help would be appreciated!
This is a known issue. There are temporary solutions posted here https://support.advancedcustomfields.com/forums/topic/google-maps-field-needs-setting-to-add-api-key/
If you are using ACF 5 Pro there is a fix for this in the new version of ACF Pro. You can get it by logging into your account and downloading from there. It is 5.4.0-beta3.
